I have a ZKK 601 in .243" and a ZKK 600 in .270". My question is this. Despite what was posted in an earlier thread if I wish to replace the set trigger with the "standard" trigger that was also supplied surely I don't need the two "U" shaped springs held in place by the two pins to the rear of, and which bear on, the set trigger?

Aren't these just for use if the set trigger is fitted? In other words with the "standard" trigger shouldn't these be also removed? So the only thing now pinned on the trigger plate assembly is the "standard" trigger alone. As on, say, a Lee Enfield?

Also in taking the rifle apart I dropped a split "spring" washer. Is this from the screw at the front or the rear of the trigger plate?

Many thanks!
